122 CATALOGUE OF BURMESE BUTTERFLIES 



284. Catopsilia crocale, Cramer, 



All Burmah. Common. Sometimes met with in immense 

 quantities after the first shower of rain in April. Females 

 show great variation in size and in the markings of the under 

 side of the hind-wings. Wet and dry season forms are equally 

 common. 



285. C. PYRANTHE, Linnaeus. 



This is a very common insect throughout the year. For 

 long I was under the impression that there must be two 

 species included under this name ; but by comparing a very 

 large number of specimens, both males and females, I find 

 that it is impossible to say to which form some of the speci- 

 mens belong, and I have been reluctantly led to the conclusion 

 that there is only one very variable species ; and though, as a 

 rule, I can at once distinguish between the two forms, yet 

 there are some males and females which I find it impossible 

 to place. Neither do the forms appear to be seasonal, as I 

 have about an equal number of each form caught during the 

 wet and dry seasons. In the form in which both sexes have 

 the smallest amount of dark markings on the upper side, the 

 spots on the disco-cellular nervules of both wings on the 

 under side are generally conspicuous; and the antennae have 

 a pinkish tinge, which often reappears about the base of the 

 costa. In the other form the dark markings are broader on 

 the upper side ; on the under side the mottlings are less con- 

 spicuous, and the spots on the disco-cellular nervules are 

 absent, while the antennae and base of the costa shew no tinge 

 of pink. 



286. C. ALCYONE, Cramer. 

 One specimen from Mergui. 



287. Nepheronia hippia, Fabricius. 



Very common about gardens and open spaces in forests 

 throughout the year. Some females are distinctly orange 

 about the base and inner margin of the hind-wings. 



288. N. VALERIA, Cramer. 



I have a male and two females which I refer to this species.
